Duplicated post – issue with scripts/gallery/lightbox

Maybe someone had this kind of problem as me.

I have an old post (https://amtuitam.pl/wroclaw/akropolis/), everything is ok, when I click on photos I open a light-box with gallery. Then, I cloned the post, the lightbox does not work, I changed nothing, just duplicated https://amtuitam.pl/wroclaw/akropolis-2/ – does anyone have an idea how to start looking for a reason and a solution? thx in advance
